i have a problem i thought someone here might be able to help with. i recently got back from gigantour, and i had a VIP meet and greet ticket. i got Megadeth to sign my 1981 Kramer. now this is the greatest guitar ive ever played, and i don't want to just put in away and not play it. it's also my only six string. but its also a collectors item, as not many were made, and with the signatures, its worth quite a bit. i CANT just put it away, but i also want to preserve the signatures. ive heard things about something called "clear coat" but i really don't know what to do here. any advice?

It is possible to put another coat on the guitar, but experienced painter is what you will need then. I don't know the costs in your country, but I reckon the paint job should be around 50-150$ depending on quality and complexity.
